Application filed November 16, 1925. Serial No. 69,292.

This invention relates to an improvement barrels used in oil shippingand the like, the primaryobject of the invention being to provide animproved construction of closure seat with which a plug or closuremember is vAnother object of the co-operable. V invention is n providingan improved method ofsecuring the closure seat to the barrel.

A further object of the invention is in providing an improved method ofinterengaging portions of the barrel with the closure seat forpreventing the closure seat being turned during the mounting or removingthe lu to or from the closure seat,

A still further object of the invention is in providing stiffening meansto the barrel i material surrounding the closure seat.

Other and further obJects will appear in the specification and bespecifically pointed Y fying the invention,

said opening i being tion4 of the closure seat out in the appendedclaims, had to the accompanying reference being drawings, exempliand inwhich Figure 1 is a vertical transverse section taken through a portionof the barrel head showing this improved. closure seat thereto.

secured Figure 2 is a fragmentary plan view of is a fragmentary 'planview of a portion of the barrel head which surrounds the openingprovided in the head and showing portions formed in the head forco-operation with theclosure seat.

Referring by numerals to the accompanying drawings, sheet metal barrel 1designates a portion of .a head having an opening 2 formed therein, thematerial surrounding depended downwardly forming a neck 3, and mountedin said opening is a depending annular portion 4 of a closure seat 5,said portlon 4 being threaded interiorly as designated at 6.

The closure seat 5 isprovided with a plu- -rality of elongated openings7iwhich arearranged circumferentially in the horizontal fiange'i ingsbeing for the reception ofraised portion 8 rel head 1. The from thecountersunk rel*head 1.

.Mounted over adapted to be rolled over the lower of the portion 4 eachof said opena respective which is formed on the barraised portions 8 areformed portion 9 of the barthe depending annular por- 5 is a collar 10,and edge of pending neck, a closure seat havin In theuse of the ordinarytype of closure seats with a co-operatmg plug, large wrenches areengaged on the plug with considerable force, and quite often the sealingconnection of the closure seat With the barrel isbroken, and the closureseat permitted to turn in, the barrel opening thus making it difiiculttoremovethe plug as well as causing a leak between the barrel head and theclosure. seat. With this improved closure seat. the seat will beprevented from turning by reason of theraised portions 8 being ininterengagement with the openings 7 of the closure seat, and the plugcan always be tightened ,or removed in the closure seat withoutloosening the seat and causing a leak. t For providing means forsecuring an identifying tagor the like to the barrel, or for sealing theplug to the closure seat, a portion 11 of the flange 7 adjacent one ofthe openings 7 is bent upwardly, thereby providing an aperture 12between the barrel head 1 and theportion 11, said aperture being for thereception of the wire fthe indentifying tag.

If it is desired a is obvious that a gasket,
